They can be defined as physico-chemical parameters and hydrodynamic parameters. The latter depend on the operating conditions of the floatation machine during the enrichment process. The process of forming of durable flotation aggregates is preceded by generation and dispersion of gas bubbles in the flotation machine tank which also depend on the aforementioned parameters. The paper presents the results of experimental analyses of changes of selected values which define the size of air bubbles generated in the flotation chamber.","author":[{"@context":"https://schema.org","@type":"Person","name":"Anna Młynarczykowska"}],"contributor":[],"dateCreated":"2024-07-24","datePublished":"2017-01-01","headline":"Analysis of the Gas Phase in Flotation Process.

It separates minerals on the basis of differences in surface properties. It is important to study the chemical and physicochemical properties of mineral surfaces. The process involves injection of air bubbles into a moving stream of aqueous slurry containing a mixture of particles. In the process only hydrophobic ores are collected on the bubble surface and exit the stream. According to the investigations reported by various researchers, it is envisaged to have adequate characterization of the system under consideration. Important factors in characterization includes solid phase, aqueous phase with solutes, gas or the second liquid phase, the three kinds of interface and interline, flow and force parameters and end products. The dispersed-air flotation looked preferable than dissolved air flotation. Gas hold up, superficial velocity and bubble size are important factors in column flotation.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline

class="ds-related-work--abstract ds2-5-body-sm">Stability of bubble size in the pulp zone and froth control is an important parameter for a successful flotation process. The present study compares the action of the main frothers in terms of: mean bubble size in the pulp zone, froth stability, surface-tension-lowering ability and reagent participation in flotation of a naturally hydrophobic mineral. Bubble size was determined using a new technique adapted from HYDROMESS, a device designed to measure drop size. The remaining indicators were obtained by determining surface tension and conducting flotation tests with the addition of hydrophobic (graphite) and hydrophilic (calcite) particles. The results indicate that methyl isobutyl carbinol (MIBC) is the most efficient frother in controlling coalescence, with critical coalescence concentration (CCC) reached at 20 ppm. Moreover, this frother has greater potential for selective action, since it increased calcite entrainment by only 2.3% at a concentration of 30 ppm. In flotation tests...</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button"
